Which orbital does the last electron of cesium (Cs) occupy in its ground
state? What quantum numbers n and l are associated with this orbital.
Solution:
The electron configuration for Cs is [Xe]6s1
Therefore, last electron of Cs is in the 6s orbital. The first number refers to the n level. n=6, the letter is associated with l sublevel.
s means l=0
p means l=1
d means l=2
f means l=3
Since the letter is s that means that l=0. For an electron in 6s, n=6, l=0.
